FEEDER non moor norms.

Application filed December 23, 1921. Serial No. 524,460.

I To all whom it may concern Be it known that ERNEST J. TURNER andBLOOMFIELD H. HOWARD, citizens of the United States, residing,respectively, at Pittsburgh, county of Allegheny, State of Pennsylvania,and city of Washington, District of Columbia, have invented certain newand useful Improvements in Feeders for Ingot Molds, of which thefollowing is a specification.

Our invention relates to improvements in feeders for ingot molds.

The object of our invention is to provide a feeder for ingot molds whichhas a certain amount of flexibility, and yet at the same time having thenecessary strength to Withstand the strain of the molten metal thereon,and should it crack, it will not separate and allow the molten metal toflow therefrom.

Another object of our invention is to pro vide means whereby the samecan be manufactured with the thinnest possible walls practical tomaintain sufficient heat to prevent piping, segregation and the like inorder to save material in the manufacture thereof, and also saving inweight in transportation, and yet maintaining the strain of the moltenmetal and at the same time providing a feeder which can be used on moldsof slightly varying sizes.

A further 0b ect of our invention is to provide a simple", cheap andefiective feeder of this character having certain details of structureand combinations of parts hereinafter more fully set forth..

In the accompanying drawings- Fig. 1 is a perspective view of the upperend of an ingot mold showing our improved feeder applied thereto.

Fig. 2 is a top plan view of Fig. 1.

Fig. 3 is a top planview of a modified form. 1

Fig. 4c is a side elevation, partly in section of a still furthermodified form.

Fig. 5 is a perspective view of a still further modified form ofretaining member for the feeder.

Fig. 6 is a perspective view of another modified form of retainingmember.

Fig. 7 is a perspective view of another modified form of retainingmember.

Fig. 8 is a vertical sectional view showing another form of feeder.

Fig. 9 is a vertical sectional view showanother form of feeder.

1g. 10 is a vertical sectional view similar to Fig. 9, showing theretaining member turned upside down, and wedges used to tighten same.

Fig. 11 is a top plan view of another modified form.

Fig. 12 is a side elevation of Fig. 11, and

Fig. 13 is a sectional View showing the retaining member extending intothe upper end of the mold.

Referring now to the drawings, 1 represents the ingot mold which, asshown, is of any ordinary form, and into which fits the feeder 2 whichis provided with the'ribs 3, which rest upon the upper end of the ingotmold and prevents the feeder from passing into the mold beyond a certainpoint. In feeders of this character, in order to save material and alsoweight in transportation, the walls between the ribs are madecomparatively thin, and it sometimes happens that these walls give wayunder the tension and weight of the molten metal before it hardens andallows the metal to flow over the mold and is wasted, and which forms adefective ingot. In order to strengthen the feeder we provide a membermade in two sections 4 and 5 hinged together at 6, and having at theirouter free ends the outward turned hooked ends 7 and 8, which areobliquely arranged, and over which fits the wedge shaped locking member9, which has inwardly turned ends adapted to interlock with theoutwardly turned ends 7 and 8 and draw them together to cause the memberto tightly bind around the feeder and strengthen the same. By thisarrangement it will be seen that the feeder, should it crack, would notseparate and allow the metal to flow therefrom.

In Fig. 3 instead of having the two sections hinged together, both endsare provided with the hooks and locked together by the wedge shapedmembers 10 and 11 constructed exactly like the locking member 9 of theform shown in Figs. 1 and 2.

In the form shown in Figures 1 and 5 the strengthening or reinforcingmember in stead of being a plain, narrow band are prov ided with thedownwardly extending apron portions 12, 13, 14, 15, 16 and 17,

which engage the thin walls of the feeder between the ribs and ive agreater support thereto to prevent t em from crum ing under the tensionand weight of the molten metal of the ingot. In this form, the wedgingor locking member 18 is constructed the same as that shown in Figures 1and 2, and the o oration is the same.

In *igure 6 instead of having the two sections hinged, as shown inFigures 1 and 2, the two sections of the reinforcing member are madeL-sha ed, and hinged together at the corner as in icated at 19, and thefastenin means 20 is arranged at the corner. In this form there areprovided the four downwardly extendin apron portions 21, 22, 28 and 24arran 'e for the urpose described in res ect to igures 4 ancl 5.

In ig. 7 we have provided a band made solid which has uplwardlyextending arms 24', 25, 26 and 27 avin their upper ends turned inwardlyas in icated at 28, and which extend over the upper end of the feederand supports the same, and which like in the other forms, tprevents thespreading or so arating of the eeder should it crack.

11 the orm shown in Fig. 8 we provide a plane continuous metal member 29of an internal diameter slightly greater than the external diameter 0the feeder and tightly clamped thereon by the wedges 30.

In Fi are 9 the internal wall of the band 31 is sli gitly ta ering, asindicated at 32 and which a lows 0 its insertion over the 11 per end ofthe feeder, and allows it to be tig tly driven down into the positionshown in Fig. 9.

n Figure 10 the same member is em ployed, but it is inverted, and wedges33 are emplo ed to lock the same on the feeder, and where )y the samemember can be used on feeders of slightly var ing sizes.

In Figures 11 and 2 we have shown the feeder 34 of a slightly differentform, and the member 35 is made of a shape to correspond thereto, andbeing made of a single piece of metal having its ends secured to--gether by the clamping member 36 constructed the same as that shown inFigures 1 and 2.

In Figure 13 we have shown the aprons carried bythe bands, as showninFigures 4 and 5, and extending into the upper end of the mold,andwhereby the apron is supported or held against outward movement andthe feeder more firmly held in place should it crack under the heat orstrain of the molten metal.

Claims.

1. A feeder for ingot molds comprising a tubular body ortion ofrefractory material and a remova le reusable metal reinforcing memberaround the same.

2. A feeder for ingot molds comprising a tubular body portion ofrefractory material, ribs projecting outwardly, and a removable metalreinforcing member extending around the same and closely embracing thecontour of the body portion and the ribs.
